ECG stands for electrocardiogram and is also known as EKG. ECG refers to the small voltages (~1mv) found on the skin caused by the sinus which is the heart's pacemaker. ECG electrodes usually come as 3,5 or 10 lead. These are:

3lead - Left ARM or LA, Right Arm or RA, and Left Leg or LL
5lead - additional leads of Right Leg or RL and V for Chest
10lead - additional leads of V1-V6 replacing the V lead, with each V lead being placed between the ribs

The health and function of the heart can be measured by the shape of the ECG waveform. Typical heart problems are leaking valves and blocked coronary arteries.
